Question about 1997 Chevrolet S-10 Pickup

Open Question

I have a 97 s10 that is blowing white smoke, and antifreeze was tested for exhaust gases...positive for them..truck sputters mainly at start up. I was told it was a head gasket, however it has not been over heating according to the gauge. would a disconnected hose to the crankshaft from the air hose cause all of this? Ive also been noticing some gurgling in the dash..is there anything else that could cause a positive antifreeze/exhaust testing? The truck was running so much better after spark plugs were changed then all of a sudden had the smoke appearance..

Almost sound like the problem is a head gasket. Is the oil a milky color? if so that is water in the oil and you have blown a head gasket.

SOURCE: 95 GMC Jimmy 4.3l W vin rough idle

My problem was solved when I repaired my 4 wd activation dash switch. The switch was contacting on 2WD & 4HI at the same time. The front differential activation is vacuum activated possibly creating a tug of war that didn't actually engage it but drained off vacuum from the engine? A theory at best but stumbbled across it because I knew the switch wasn't working properly I repaired it and low and behold rough idle disappeared and all is good for 3 weeks running.

1- check there is spark come from spark wires
2- check the fire timing by looking for every wire in the right place
3- check there is injector signl
4- check for any vacuom leak
5- try to clean the MAF by brake and parts cleaner

SOURCE: white smoke from exhaust

Hello;
The white smoke is from coolant entering the combustion chamber(s). Coolant can enter through the water passages sealed bu the head gasket. You have probably blown a head gasket. You should check your coolant level. You may have acracked head if you continue to drive it and overheat. The temp gauge only reads when exposed to coolant, not air. Take out thhe spark plugs and look them over. A white glossy apperance will indicate water in the combustion chamber. You may need to surface the head once you have it removed so that it is flat. Hope this helps.
Thanks;

SOURCE: My 2000 Chevrolet S10 ZR2,

I have done a full engine replacement on these, a zr2 to be exact. I have found that a p0300 (multiple misfire) usually points the the Piece of **** injection spider, then I had a p0301 as well after replacing that with the multiport unit upgrade and found that the spark plug electrode folded over shorting to the center conductor.

Acura rl 3.5 antifreeze pushed out reservoir cap. no white smoke out back of pipe when starting


Blows out? Probably a head gasket. they don't always blow white smoke. Parts store sell a kit to check exhaust in the reservoir or radiator. Best bet. If it blows out, Fill it with water, leave the cap off. Start it and put your hand over the reservoir opening. You feel any pressure being cold. Head gasket.

When you say "sometimes", whad do you mean exactly? When cold? When warm? When accellerating?
White exhaust smoke (which has a sweet smell) is often an indication of a blown head gasket. You'll need a compression test or test the antifreeze against exhaust gas contamination. Although the compression test will tell you more about the contition of the head gasket.
Where exactly does the white smoke come from under the hood? Maybe there's a puncture somewhere on the radiator hose or heater hose and the antifreeze sprays on the exhaust? Please check. There still is a tiny bit of hope it's not the gasket...

X-Trail has white smoke blowing out exhaust pipe when I start up


It's normal for cars to do this in cold weather til the engine warms up a bit. If it's not cold you might have a head gasket going bad causing antifreeze to get into the engine.

How do I locate a leak that lets antifreeze and oil mix inside the oil pan?


Most likely a head gasket. The coolant is forced into the oil chambers and mixes. This too leaks into the exhaust gases and burns off as you describe. You usually get oil in the coolant reservoir. This can be checked with a test strip available at automotive supply store. It measures the acidity in the coolant.

Yesterday I purchased a 97 Toyota Camry and when we test drove the car it ran smooth and had no problems. after we purchased the car we put gas and started to drive home about half way home when I stoped...


If your test drive was short, but your drive home is longer, it could be a coolant leak. Coolant creates a thick white smoke when it burns. If it's coming out of the tailpipe, then it must be coming through the engine at some point, possibly from a failing head gasket.

A fairly inexpensive test for this is to drain and flush the radiator, refilling it with water, running the engine to warm it up, then drain and flush again, refilling it with water. Be sure to drain and flush the overflow reservoir as well if you can. And please be careful working with a hot radiator - steam burns skin very easily. This should remove at least 75% of the ethyl glycol antifreeze that causes the smoke.

Now, when you run the car up to temperature, if it still smokes white, but much, much less, then it is in fact coolant leaking into the engine and being vaporized and pushed out through the exhaust. The most likely point of failure is the head gasket - which means a several hundred dollar fix.
